 Description   

Send notification via Telegram bot with message containing "<"
for example:

<b>PROBLEM DETECTED</b>\nMy host\r\n\r\n<b>Warning</b>\r\nHost has been restarted (uptime < 10m)

Sending will fail with
Sending failed: Bad Request: can't parse entities: Unsupported start tag "" at byte offset xx
Telegram bot after < waits for the tag but it's not a tag it's "less"

Need to replace < to < with correct regex
https://core.telegram.org/bots/api#html-style
Although for > it works
